To all whom it may concern:

Be it known that we, \Vtmimiu Au'rmin 5 Bomz, resident. of the Uni versity; Leeds, in theeounty of York, England, professor of applied. chemistry, JA nits 'uinm n W insoxJ resident of Carlton Works, Ari'nley, Leeds, in the sai'd'eounty, gas-stove manufiwturer, and Crew Done-ms )IeCoymx' resident of 1-3 M'alwoodgroad, 'Balham ll ill, London, S.

rounding the tubes. The I increased heart 66 transfer appears to be due partly to the fact that the heated granules radiate heat to the walls of the tubes, and partlyto the churning md batliine action which the fragments exerei e on the flowing gas; The part played by radiation will depend onthe tomperature at; which the hot gaseous products enter the tubes.

l-Ve have" previously described and hown a hoiler'proyided with-t|1bes.p'acked with, granular materialadapted to amelerate the, eomlmstion of an explosive mixture of suit- The present invention differs 70 purpose of the tubes and granular'materiah therein being to transfer theheat mm; hotj gaseous products only to thewaterinfthe holler. i v l n the boiler tubes. T the granular material is retained'by means of-fen ulesI org plugs l of fireelay or the like at one end and by spiders or grids S at the 0thr1nd the aperture 1. in plug I. beingaslargeas i ossible consistent with retaining thegranules in position. While granules of a some-1 what larger size may he used in the, front end .(see' Fig." 2) thesize we -prefer to adopt one whieh will pass a sieve of one megh. to the linear ineh but. which will not pass a" sieve of two meshes to the linear inch, )ther sizes however may be employed, and; we have found that as the size ofthe granules inereases the resulting heat transfer 1'. unit. area of tube surfaee decreases, as 005 also the resistance to gaseous flow exercised by the granules. llenee. if larger granules be employed it will be found desirable to in- (H-USE the length of the boiler tubes. The granular mater al must be sutlieiently r01 fraetory to stand tlidteinperatm e produced in the hottest pa t qt the tube, and in gens eral may consist of;firebriekcrushed and meshed to the required size.

The tubes 'l" in the heater F de not require the plugs 1, simple spiders orgridss' will answer the purpose. The water to the heater I is by preference caused totak 'a' sinuous course-around the tubes T',"bafil e' plates (1 being arranged as shown, or in any other eonvt'enient orusual manner, the ar rows indicating a suitable direction of flow of feed water.

i tur'e ofa smoke box having doors or the like H. ".The chamber, H communicates with the" exitv en ran or other exhausting appliance by which I When the said diameter of tubes is increased it be found desirable to increase considuniformly along the lengt tubes-may be provided with fire clay or like pushed home by the. disk, a rotatory or heater into the boiler in any ordinary or length and 3 inches internal diameter, longer chamber, an exhaust passage communicat- The gaseous p'roducts are led from the usual tunnel or the likeID to a firebrick' 'or like chamber provided with suitable means of access to the tubes and boiler at the boiler front; The rear ends of tubes T give admission into a chamber H in the nachamber J hayinga door or doors in or at J a passa e,'pipeior the like K leads from (50f the tubes T of the heater F and inthis passage is arranged --a' suitable the hotgases are drawn through the boiler and heater.- I I The feed water will be passed through the well known manner.

It will be seen that whilea boiler adapted as hereinbefore described may have a com-' paratively large diameter, the length thereoi. need only tbegcomparatively small, but while we have mentioned tubes of 3 feet-in or shorter tubes may-be employed with an increase ordecrease in the diameter thereof.

erably' the length thereof, and where these In or and longer tubes areemployed, and-it is desired' to spread the'evaporation more h of tubes, such linings or sleeves adjacent to the ferrules P and continue some distance along the tubes.

With regard tothe pr cking of the tubes with granular refractdry material, when such tubes are arranged vertically same-may be evenlypacked by merely dropping; the granules therein but where the tubes are ar ranged horizontally as in Fig. 1 this method will not apply. In order to pack the tubes evenly we use a special tool, (see Figs. 3 and 4) comprising. a disk- L having fingers or projections L near its periphery the disk bcingmounted on a convenient handle. The

anular material is placed in the tube and semi-rotatory motion being given thereto. This action is continued until the tube is filled.

Instead of irregularfragments being employed as a granular acking for the tubes fire clay balls or the ike of a suitable size may be employed.-

What we claim as our-invention is a 1.'-' In water heaters, ajheater inlet cham ber adapted to receive hot'gases, a series of substantially" vertically arranged heater tubes communicating with said heater inlet ing with the discharge end of said heater tubes and "an exhaust fan connected with said exhaust passage to draw the cooled gases therethrough and down through said heater tubes, each of said heater tubes be ing packed with granular refractory material of betweefi' about one-half and one inch mesh and means including a series of horizontal bafiies to pass the feed water through said hegter around said tubes in a sinuous upwa i'r iiilirection.
